Unsteady flow of nanofluid through porous medium with variable characteristics

Salient characteristics of activation energy and porous space on unsteady flow of nanofluid are analyzed. Flow in porous space is characterized with Darcy-Forchheimer relation with variable porosity and permeability. Disturbance in flow is caused by a stretchable rotating disk. Brownian motion and thermophoresis are also accounted. Features of heat transfer in flow of nanofluids are more prominent in industries and technological advances. Transportation, atomic reactors, hardware, vitality and medication are few such processes. Appropriate transformations are adopted for reduction purpose. Numerical solutions of resulting nonlinear system are computed. Graphs are plotted to interpret the impacts of sundry variables on velocities, temperature and concentration. Physical quantities are analyzed through numerical results. It is observed that velocity through porosity and local inertial parameter has opposite trend.
